Adapteva Joins The Kilocore Club With Epiphany-V
The computing industry is facing a number of challenges as Moore’s Law improvements in circuitry slow down, and they don’t all have to do with transistor counts and memory bandwidth and such. Another problem is that it has gotten progressively more costly to design chips at the same time that mass customization seems to be the way to provide unique processing capability specifically for precise workloads.
In recent decades, the US Defense Advanced Research Project Agency pumped huge sums of money into designing and manufacturing gigascale, terascale, and petascale systems, but in recent years this development arm of the US …

Sprint Launches SD-WAN for Global Enterprises

Real-time domain name lookups
First, use the dns.servers System Property is used to specify one or more DNS servers to handle the reverse lookup requests. For example, the following command uses Docker to run sFlow-RT with DNS lookups directed to server 10.0.0.1:
docker run -e "RTPROP=-Ddns.servers=10.0.0.1" \The following Python script dnspair.py uses the sFlow-RT REST API to define a flow and log the resulting flow records:
-p 8008:8008 -p 6343:6343/udp -d sflow/sflow-rt
#!/usr/bin/env pythonRunning the script generates the following output:
import requests
import json
flow = {'keys':'dns:ipsource,dns:ipdestination',
'value':'bytes','activeTimeout':10,'log':True}
requests.put('http://localhost:8008/flow/dnspair/json',data=json.dumps(flow))
flowurl = 'http://localhost:8008/flows/json?name=dnspair&maxFlows=10&timeout=60'
flowID = -1
while 1 == 1:
r = requests.get(flowurl + "&flowID=" + str(flowID))
if r.status_code != 200: break
flows = r.json()
if len(flows) == 0: continue
flowID = flows[0]["flowID"]
flows.reverse()
for f in flows:
print json.dumps(f,indent=1)

Announcing Docker Global Mentor Week 2016
Building on the the success of the Docker Birthday #3 Celebration and Training events earlier this year, we’re excited to announce the Docker Global Mentor Week November 14-19, 2016. This global event series aims to provide Docker training to both newcomers and intermediate Docker users. More advanced users will have the opportunity to get involved as mentors to further encourage connection and collaboration within the community.
The Docker Global Mentor Week is your opportunity to either #learndocker or help others #learndocker. Participants will work through self paced labs that will be available through an online Learning Management System (LMS). We’ll have different labs for beginners and intermediate users, Developers and Ops and Linux or Windows users.
Are you an advanced Docker user?
We are recruiting a network of mentors to help guide learners work through the labs. Mentors will be invited to attend local events to help answer questions attendees may have while completing the self-paced beginner and intermediate labs. To help mentors prepare for their events, we’ll be sharing the content of the labs and hosting a Q&A session with the Docker team before the start of the global mentor week.
Sign up as a Mentor!
